vscodeですかね？
ひとまず赤波線をマウスオーバーした時に、ポップアップか何かが出ませんでしょうか？
あと、main.cppのコンパイルはできますか？
コンパイルエラーになるようであれば、そのエラーメッセージには何が書かれていますか？

競プロのための環境構築がうまくいきません
解決したいこと
競プロに興味を持ち環境構築を始めたのですが、#include <bits/stdc++から永遠に赤線が取れません。
様々なサイトを参考にしたのですが、どのサイトも少しずつ違うことが書かれておいり、何が原因かもはっきりしません。
発生している問題・エラー
main.cpp
#include <bits/stdc++.h>
//ここにずっと赤い波線がで続けています
using namespace std;
int main(){
int N;
cin >> N;
vector<int> A(N);
for (int i = 0; i < N; i++) cin >> A[i];
for (int i = 0; i < N - 1; i++) cout << A[i] * A[i + 1] << " ";
}

自分で試したこと
homebrewのインストール
homebrewは見当たらないが、brew install gccは機能する状況
gccのインストール
上記の通りbrew install gccでgcc-13、g++-13を/usr/local/binへ入れることはできた。
which g++-13
/usr/local/bin/g++-13
which gcc-13
/usr/local/bin/gcc-13
シンボリックリンク
実行したコマンド
ls -s /usr/local/bin/gcc-13 /usr/local/bin/gcc
いまだにgccとgccのふりをしたClangの見分け方がわからないがおそらくうまくいっていない。現在gccと実行すると下のようになる。
/usr/local/bin/gcc-13
gcc-13: fatal error: no input files
compilation terminated.
gcc
gcc: fatal error: no input files
compilation terminated.
情報の過不足等流かと思いますがよろしくお願いします

Questionerご回答ありがとうございます
ポップアップとエラーです

こんな感じです！
システムヘッダーの一部が見つからないようですね。
おそらくincludePathに不足があるのだと思います。こちの記事を参考に、不足しているパスを探してみてはどうでしょう。
自分はc++-13を使っています。
brew install gccでインストールしたディレクトリのbinにいると思います（g++-13と同じディレクトリ）。
それを/opt/homebrew/bin/c++-13にシンボリックリンクして、
さらにalias gcc="c++-13"で、gccとしています。
（上のmain.cppをgcc main.cppでコンパイルできました）
% which gcc
gcc: aliased to c++-13
% which c++-13
/opt/homebrew/bin/c++-13
% c++-13 -v #gcc -v も同じ
Using built-in specs.
COLLECT_GCC=c++-13
（中略）
gcc version 13.2.0 (Homebrew GCC 13.2.0)
元々の gcc が、clang です。
% unalias gcc

Questioner色々試してるのですがどうしてもダメです...
今の所標準ライブラリがincludeできていない説が濃厚だと思うのですが、特に標準ライブラリがXcode周りのディレクトリにあるせいで、変な挙動になっているのかな？と思っています。
Xcodeはダウンロードしているでしょうか？
Xcodeもインストールしてあります。
